Application .tiled April 8,

To u-Z/ who/111 if III/HL/ cnImcrIL:

Be it known that l, Jonx Aunnosa lion- LOWELL, a citizen of the UnitedStates, and a resident of Memphis, in the county of Shelby and State of'lennessee, have invented a new and linproved Candy-Forming Machine, of

which the following is a full, clear, and exact descriptlon.

The ()lUGCf of the invention is to provide a new and improved machinemore especially designed for forming the plastic candy material intosticks of any desired shape'and size and cutting the stick transverselyinto pieces of the desired length.

The invention consists of novel features 3 and parts and combinations ofthe same, as 1 will be more fully described hereii'iaft-er and thenpointed out in the. claims.

A practical embodiment of the invention.

is represented in the accompanying drawings, l

forming a part of this specification, in which similar characters ofreference indicate corresponding parts in all the views.

Figure 1 is a side elevation of the improvement. Fig. 2 is a sectionalside elevation of the same. Fig. 3 is an enlarged side elevation of thetwisting device. .Fig. 4 is a plan view of the same, parts being insection. Fig. 5 is an enlarged sectional plan view of the improvement onthe line 5 5 of Fig. 1. Fig. 6 is a cross-section of one of thetwistingrollers and the driving parts connected therewith; and Fig. 7 isan enlarged sectional plan 7 view of the cutting mechanism, the sectionbeing on the line 7 7 of Fig. 1.

On a suitably constructed frame A is mounted a hopper B for containingthe plastic candy material and discharging the same downward between apair of 1n1t1al drawingrollers C C, whlch form the material mto stickform and feed it downwardly to another pair of drawing-rollers D D,which reduce the cross-sectional area of the stick and feed the latterdownward to another pair of drawing-rollers E E, employed for producinganother reduction in the size of the stick and for feeding the reducedstock downward to the final pair of drawing-rollers F F, which reducethe stick to the desired cross-sectional area and deliver the stick to atwisting def vice G, in which the stick is twisted, the twisted stick onbeing discharged from the twisting device being cut into the desiredlengths by a cutting mechanism ll.

The pairs of rollers C C, l) l), l l5, and

Specification of Letters Patent.

l F F are graduated lhal is, decrease in, size, but are rotated with anincrease in speed in proportion to the decrease insize. The rollers ineach pair are in rolling contact with each other and are formed withconcaved peripheral portions to provide drawing-openings for the passageof the material, the said openings (l(('l'ttlfill'} gradually in size ati the successive pairs of rollers to gradually re- 5 duce the stick incross-sectioinil area, as will be readily understood by reference toFig. l. 1 The pairs of rollers C C, l) I), I) E, and F F are driven in,unison and at the increased rate of speed mentioned from a pulley l,connected by belt with other machinery, and this pulley l is preferablysecured to the shaft l) of the roller l), and a suitable gearing isprovided for rotating the different sets of rollers from the shaft 1)carrying the pulley l. This gearing is arranged as follows:

()u the shaft I) (see Fig. l) is secured a pinion J, in mesh with anidler J,journaled onthe main frame A and in mesh with a gearwheel Jsecured on a shaft for. the drawing-roller so that when the shaft 1) isrotated the pinion J rotates the idler J, which in turn rotates thegear-wheel J and the shaft C to rotate the roller C, and with it theroller as the shaft of the latter is connected with the shaft bygear-wheels and as indicated in Figs. 1 and 5. Thus the rollers and arerotated at a lower rate of speed than the rollers I) and l), whichrotate in unison by having their shafts l) and I) connected with eachother by gearwheels I) and l).

l ()n the shaft I) is secured a large gearl wheel K, (see Figs. 2 and5.) in mesh with a l somewhat smaller idler gear-wheel K, mesh l l ingwith a gear-wheel 1i", secured on the shaft E of the drawing-roller E,so that when the shaft 1) is rotated a rotary motion is transmitted, ata higher rate of speed, however, to the shaft E by the gear-wheels 1i.K, and K 'lhus the roller E is rotated at a higher I rate of speed thanthe roller 1), and as the l rollers E and E are rotated in unison byhaving their shafts E and E provided with meshing gear-wheels E and E itis evident that the said rollers E and E rotate at a higherrate of speedthan the rollers l) and l). On the shaft E is also secured a largegearwheel K, (see Fig. Ll'in mesh with an idler K, journaled on the mainframe A and in i mesh with a. pinion K secured on the shaft F 2 of thefinal drawing-roller F, rotating in unison with the drawing-roller F byhaving their shafts F and F connected with each other by gear-wheels Fand F When the machine is in operation and the shaft E is rotated, asabove described, then the gearwheel K by the idler K andpinion K rotatesthe shaft F and the drawing-rollers F F at a higher rate of speed thanthe preceding drawing-rollers E and E.

By the arrangement described the material is formed into stick form andis gradually reduced in cross-sectional area. without danger ofretarding the material in its passage through the several pairs ofrollers, and hence a large amount of material can be handled in acomparatively short time.

The last pair of drawin -r0llers F F discharges the reduced stick etweena pair of twisting-rollers G and G mounted to rotate in unison and torevolve bodily around, so as to twist the stick while feeding the stickdownward. For the purpose mentioned the following arrangement is made:The twisting-rollers G and G are keyed or otherwise fastened on shafts Gand G", (see Figs. 4 and 6,) journaled in suitable bearings carried onthe upper face of a disk or flange L, held on the upper end of adelivery-tube L, the aperture of which registers with the opening formedbetween the contacting twisting-rollers G and G The shafts G and Grotate in unison with each other, and for this purpose the said shaftsare connected with each other by meshing gear-wheels G and G On theshaft G (see Fig. 4) is keyed a pinion N in mesh with a gear-wheel N,having its hub N mounted to rotate loosely on the shaft G (see Fig. 6,)and on this hub N is secured or formed a worm-wheel N in mesh with aworm N, having its shaft N disposed vertically and journaled in suitablebearings on the disk-or flange L. (See Fig. 2.) On the upper end of theshaft is secured a pinion N, in mesh with an internal annular rack Nfixed on the main frame A, so that when the delivery-tube L and its diskL are rotated then the pinion N rolls off on the fixed rack N and thusturns the worm-shaft N and the worm N which latter by being in mesh withthe worm-wheel N rotates the hub N and the gear-wheel N, so that thepinion N is driven, and with it the shaft G and consequently thetwisting-rollers G and G, as the shaft G is connected by the gear-wheelsG G with the shaft G carrying the roller G.

In order to rotate the delivery-tube L and its disk L, as abovementioned, and in. unison with the last pair of drawing-rollers F F, thefollowing device is provided: The deliverytube L is journaled insuitable bearings on the main frame A and is provided with a pulley 0,over which )asses a belt 0, also passing over a pulley secured 011 avertically disposed shaft P, journaled in suitable bear ings on the mainframe A. On the upper end of the shaft P is-secured a bevel gearwheel P,in mesh with a bevel gear-wheel P secured on a transverse shaft Pjournaled in bearings carried by the main frame A. On the shaft P issecured a pulley P connected by a belt P 'with a pulley P attached tothe shaft F of the drawing-roller F, so that when the latter is rotated,as previously mentioned, then a rotary motion is transmitted by thepulley P, belt P and pulley P to the shaft P, which by the bevelgear-wheels P P rotates the shaft P, and the latter by the pulleys O 0,and belt 0 rotates the deliverytube L, and with it the disk or flange L.

From the foregoing it will be seen that when the machine is in operationthe twisting-rollers G and G of the twisting device G are rotated inunison around their axes and are carried bodily around an axiscoinciding with that of the delivery-tube L and extending centrallythrough the opening between. the twisting-rollers G and G and theopenings between the other pairs of rollers F F, E E, D D, and C C.

The cutting device H is provided with a knife H, extending horizontallyand adapted to be moved past the lower end of the delivery-tube L, so asto periodically cut the stick of candy as the latter passes through thelower end of the said deliverytube. The knife H is secured on a bar H,(see Figs. 1 and 7,) mounted to slide lengthwise in suitable bearings onthe main frame A, and on one end of the bar H is formed an angular armHfl'adapted to be periodically engaged by the arms of a Wiper H securedon the shaft P. The bar H is pressed on by a spring H to hold the arm Hin peripheral contact with the wiper H and when the arms of the saidwiper impart a sliding motion from the right to the left to the bar Hthen the knife H is moved in a like direction to the left of the lowerend of the delivery tube L, and at' the same time the spring H ispressed, and when. the end of an arm passes the end of the angular'arm Hthen the compressed spring H causes a quick sliding movement of the barH and the knife H from the left to the right, so that the knife H cutsthe stick of candy.

In order to keep the candy material placed. in batches in the hopper Bfrom becoming hard, it is necessary to heat the hopper and the materialcontained therein, and for this purpose the hopper B is preferablyformed of-an inner wall B and an outer wall B (see Fig. 2,) the wallsbeing spaced apart, and between the spaced walls is placed a heatingcoilB connected with a boiler or other suit able source of heating medium,so that the latter on flowing through the coil B heats the latter andthe hoppel B and the material. con tained therein to keep the latter inthe proper plastic state for the material to flow through When themachine is in operation, the pair of initial drawin -rollers U C )ressesthe mao l terial into stick form and delivers the same in a downwarddirection to the next pair of drawing-rollers D D, which reduce thestick in diameter; but as the drawing-rollers D and D rotate at a higherrate of speed than the rol lers C and C it is evident that a properpassage of the candy takes place between the rollers C C and D D. Thelatter pair of rollers D D feeds the stick of candy to the next pair ofdrawing-rollers E E, in which the stick is again reduced and fed forwardat a' higher rate of speed to be finally reduced by the rollers 'F F,which in turn deliver the 1'e duced stick of candy to the rollers G Grotating in unison and turning bodily around, so as to twist the stickof candy. The twisted stick of candy is fed by the rollers G G into thedelivery-tube L, and the twisted stick of candy is cut at the lower endof the said delivery-tube L by the knife H to form pieces of candy ofthe desired length.

The machine described is very simple in construction and permits offorming a large quantity of candy material into twisted pieces of thedesired length in a comparatively short time.
